Question

what is meant by velocity

Answer 1

speed of something in a given direction is called velocity.

Answer 2

Velocity is defined as a vector measurement of the rate and direction of motion or, in simpler terms, the rate and direction of the change in the position of an object. The scalar (absolute value) magnitude of the velocity vector is the speed of the motion. In calculus terms, velocity is the first derivative of position with respect to time.
